Scope
Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: Significantly higher awareness of the construction ecosystem actors about solutions that are inspired by vernacular knowledge [1] , nature-based solutions [1] , bioclimatic design and/or frugal innovation [1] . The application of the developed solutions helps to achieve and maintain the thermal comfort in buildings while significantly reducing life cycle energy use, GHG emissions and costs compared to solutions that currently dominate the market. Scope: Reducing life cycle GHG emissions in buildings is key to meet the Green Deal’s objectives and make the built environment more sustainable [1] . However, achieving thermal comfort inside buildings with poor thermal resilience often relies on energy-intensive solutions, such as air conditioning which not only emits GHGs and represents significant energy costs, but also contributes to urban heat island effects, impacting the health and well-being in neighbourhoods [1] , particularly for groups in a vulnerable situation such as the elderly and low-income households. There is therefore a need to further develop and demonstrate the effectiveness of beautiful [1] , sustainable and affordable solutions for achieving thermal comfort in buildings that are inspired by vernacular principles, nature-based solutions, bioclimatic design and/or frugal innovation. Proposals are expected to address all of the following: Develop and demonstrate at least two solutions for achieving thermal comfort in buildings based on vernacular principles, nature-based solutions, bioclimatic design and/or frugal innovation. Demonstrate the two solutions on new and/or existing buildings – including at least one cultural heritage building – in at least two different climatic zones located in different Member States and/or Associated Countries. Evaluate the reduction in life cycle GHG emissions and life cycle costs as well as the improvement in affordability compared to solutions currently on the market. Ensure the accessibility of the solution to groups in a vulnerable situation and the aesthetic appeal [7] of the solutions developed. Identify barriers hindering the implementation, scalability and replicability of the proposed solutions, including regulatory aspects, and provide recommendations and guidance to overcome them. Proposals are expected to follow a participatory [8] and transdisciplinary approach [1] through the integration of different actors and disciplines. Synergies should be explored and, as appropriate, pursued with other …

The mix of organisations
Who coordinated them
Coordinating an EU project is a demanding, specific job. These organisations have done it on this topic line before.
This is the shape, not the consortium. It says how many partners these projects had and what kinds of organisation were in them. It does not know whether your idea needs the same mix, who is available, who is already committed elsewhere, or how the work and the budget should be divided. Those are judgement calls on a specific proposal, and no amount of public data answers them.
Building the actual consortium — finding the partners, agreeing the roles, and writing it so it survives an evaluation — is what Scientific Network Management does. Free either way; the radar does not change if you never ask.
Get told when something changes
Most institutions find out about a call with three weeks left. We write when something opens, moves or closes that fits what you work on, with the deadline, the fit and the funder's own exclusion clauses quoted. Nothing in a quiet week. Free, and one click to leave.
Starting from the programme you are reading: Horizon Europe (HORIZON) — change it below if you like.
Leave the second box empty and you get whatever opened or changed recently, closing soonest. Fill it in and it ranks against your words instead: that is the difference between a list and a shortlist.
Scientific Network Management will send you the current list for these terms, and after that only what changes: a call that opens, a deadline that shifts, a clause that rules you out. Nothing is sent when nothing has moved. One click to stop, in every message.
One confirmation email and nothing else until you click it. No tracking pixels, no sharing, one click to unsubscribe.
Of every 100 Horizon Europe proposals
A funding strategy reads your institution's own published record against the calls that are open, and says in writing which are worth the year and which to decline, with the reason for each.

SNM also does
No obligation, and nothing here is conditional on using us: searching the calls stays free and asks for nothing either way.
